which inequality represents the following situation 3/5 times 5 less than a number is no more than 27
andrey2020 [161]

The answer is \frac{3}{5}(x-5) \leq 27


Let's build the expression piece by piece, translating sentences into formulas:


"3/5 times..." \to \frac{3}{5} \times \ldots


"5 less than a number..." \to x-5 \ldots


So, the first block becomes


"3/5 times 5 less than a number..." \to \frac{3}{5}(x-5) \ldots


"...is no more than 27" \ldots \leq 27


So, putting the pieces together, you have the answer

AleksandrR [38]
Find the circumference of one wheel and then mult. that by 18:

C = 2*pi*r         becomes    C = 2*pi(1.14 m) =  2.28*pi m

Distance traveled:        18*C = 41.04*pi meters, or approx. 129 meters

If 1 factor of 6x3 + 23x2 − 6x − 8 is (x + 4), what are the other 2 factors?
spin [16.1K]
Use synthetic division to find the quadratic:

-4 | 6 23 -6 -8
6 -24 4 | 8
—————-
6 -1 -2 | 0 = 6x²-x-2 = (3x+1)(2x-1)

So the other two factors are 3x+1 and 2x-1.
